Turbo Flame Lighter
I got a turbo flame lighter a few years back:
Recently it started to get problems, the ignition failed to spark.
Today I opened it up, turned out the plastic inside the piezo ignition is broken, causing it to fail. The plastic is very thin and weak and will easily break on either impact or repeated use.
So do not buy this lighter, it looks very strong and robust. If warm enough it give a nice burn, but with frequent use it will die very quickly.
Next thing I am gonna try a fire-steel.
